Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated over the outer circumference and shoulder of the tire, the opposite side being the same as that illustrated; and,

FIG. 2 is a enlarged fragmentary front elevation view of the tread pattern thereof.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 1.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
